Improvement in railroad snow-plows



PATENT QFFICE.

WILLIAM DAVIS, OF FIVE CORNERS, NEW YORK.

IMPROVEMENT IN RAILROAD SNOW-FLOWS.

Specification forming part of Letters Patent No. 136,975, dated March18, 1873.

To all whom it may concern:

Be it known that I, WILLIAM DAVIS, of Five Corners, Cayuga county, Stateof New York, have invented certain Improvements in Railroad Snow-Flows,of which the following is a specification:

The object, of my invention is to remove snow from the rails, especiallysnow-banks and drifts of snow in large quantities, which have hithertoproven the great obstacle for the progress of the trains, and for whichthe heretobefore used expediences have proven inefficient.

In order to describe my invention more fully, I refer to theaccompanying drawing forming a part of this specification.

Figure 1, Sheet 1, is a side view of a railroad snow-plow embodying myinvention. Fig. II, Sheet 1, is a back 'view of the same. Fig. III,Sheet 2, is asectional view through line a; a", Fig. II.

A is an inclined frame, to the front of which is attached the smallerrailroad wheels B B, and to the rear of the same the larger railroadwheels 0 0, all on suitable axles and in suitable bearings. To one endof the smaller wheel-axle is fastened a gear-wheel, D, which works intothe gear-wheel E, which in revolving, also revolves the pulley or wheelF attached to the same, and, having spurs a a, revolves the belt I).This belt, being attached to the pulley or wheel G, also provided withspurs (1, causes the axle H to revolve. This aXleH, placed in front ofthe inclined plane A, is lined with a number of cutters, e e, which inrevolving break the banks or drifts of snow. To one end of the axleofthe large wheels 0 O is attached a gear-wheel, I, which in revolvingalso revolves the gear-wheel J, which is attached to the axle f. To thisaxle f is fastened the two beveled'gear wheels g and h, which work intothe beveled-gear wheel z, and can be drawn out of orin gear by aid ofthe lever j. A gear-wheel, K, attached to the beveled-gear wheel 1'works into the gear-wheel M, which is attached to an axle, L, to whichare fastened the pulleys NN with spurs m, which revolve the belt 0, thesame being pierced with holes 0. To this belt are attached the lathes orshovels p 12. To the axle f is also fastened the gear-wheel P, whichworks into the gear-wheel Q, and thus into the gear-wheel. R, which isattached to an axle, q, placed on the top in the rear of the inclinedplane A. On the other end of this axle q is fastened a pulley, S, withspurs r r, which cause the belt in front of the locomotive, and is thusdriven into the snow covering the rails. The cutters c in front,revolving, naturally serve to break up the packed snow, which isforcedby the forward movement of the plow upon the inclinedplatform U,from which it is further forced up on the belt W, which by aid of theshovels V V carries the snow upon the-inclined plane and deposits itupon the belt 0, with the shovels p p, which in revolving carry the snowto either side of the track, as desired, which is done by shifting thelever J.

Having thus fully described my invention, I desire to claim The breakere, incline platform U, belts W O, with shovels V and P attached thereto,in combination with the incline frame A, driving-wheels BB and G O,pulleys S T N N GF, gear-wheels D E I J1 Q R K M, bevelgear wheel 9 h i,and boards a and u, substantially as and for the purpose hereinbeforeset forth.
